Sanyo DP42746.Can't get tv to come on. The green power LED is on.

have a sanyo dp42746 will not turn on . green light on back off set flashing 12 times but tv. will not turn on

open back panel and look for error code

to test all y sub boards remove the main power connection to the y main and turn the tv on if it powers on one of those boards are bad.. remove both sub boards. and plug in the y main. if it powers on then that board is good either, put your multimeter on 2k omh and test the upper ysub boards black connector, the top 2 pins with negative to the 5th pin positive. you should read 500-1k ohm if its way under 100 there is a short.

the bottom ysub board place the multimeters black probe on the bottom 2 pins of the black power conection and the red on the 4th pin.. results are the same.

low resistance means theres a short in the board.

Check the inputs on your TV, are they correctly inserted? Is there a device connected to them? Try to change the input on your tv.
If this problem persists, it is your power supply failing, and your tv needs maintenance.

Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

1.You have a power supply issue on the main board of the TV.
Your TV will need service.
2.the inline protection fuse or the rectifier circuit has malfunctioned ( weak or bad) component and need replacement parts.
3. the clicking sound is the start up circuit but the voltage signal sent to the next circuit is not received therefore the system in not activated.

Usually a power issus are a power suppy issue or main board issue. If unit or pilot lights do not light happens.

lets get together, start a list of names and sue companies selling crappy wares at way too high prices! email [email protected]

Anyone have a suggestion for this? This thing is a year old and is kaput.... anything????
